To all whom it mqy concern:

4 Be it known that I, WILLIAM L. Moanrs, a citizen of the United states, residing a Chicago, in the county of; Cook and Sta-W 0f Il1inois, have invented certain new and useful Improvements in. Clariiyingsystems for Oils and the Like, of which the iollowing is a full, clear, and .oXfACl descripti mi The invention relates to clarifying sysems for oils an the ke, an .wraratu adapted for use in connection therewith The primary'ob'jec't oi the invention is to provide an improved system and apparatus for clarifying oils andthe like'conrprising.

such apparatus as, will enable oil or other liquids to precipitate their heaVie'r-in purL ties and heing provided with improved 11 means for bringi these impurities t'o some one or rnore predetermined points the sys-.

tern where the impurities may beremoved.

A further. object bithe invention is to provide, in a system of the describedcharfo m t-g a ty tank indi a e y h ref r-- v refuse tan k.

acter 'fior clarifying oils and other liquids, iinpr'oved means whereby the'clarified'portion of the oilsor other liquids returned asprecipitationlmay he returned to the if'desiredefler-beingclar fied.

The invention further consists in details system,

Patented Mall,- 25, 1913, l lame ar a ay 8 we sp rm no. momtom thereof as illustrated. 18 is a nmp which is shown diagrammatically an may beof any desired construction and operated either by hand or power. 19 is the-regular discharge, pipe within the drip receiving tank l7 and the intakeQO'of the 'sarne is located preferably as illustrated" somewhat above the bottom of the tank in. order that;v the heavier portions of the drip at the-bottom may nothe disturbed by'the outflowing dis charge. This regular discharge pipelll is provided wit-h'a suitable-control, valve 21 and leads to the pump" 18. Leading also to the pumpl8'is the low down cleaniouhsuction pipe 22, thedower extremity 23 of which I serves as an intake and-is preferably adiaoent a depression in'the botthm, of the tank 1?, as indicated at- 24. A convenient air-- 'rang'ement of'the pipes within tank 17 that illustrated in which the pipe'22 leads directly upward to the pump and the regular discharge pipe 19 isftapped into it at 2 5 above the valve 26 controlling the low down clean out. Thepurnp 18 is provided with a.

discl-i'arge pipe a at 27 controlled by a suitable closing valve 28v and discharging' up-.

Wardly into the gravity tank l0.- 'lhe main refuse tank is indicated by the reference character 29, it being preferably a" closed tank, as illustrated, of any suitable construe tron adapted to receiy e the dirty 'deposits from the other parts of the system. l.he precinitation tank 13 is provided Wiiha draw-0H 30 composed of hand operating valve 31 and discharging into a suitable drain, as indicated at 32, being preferably in the form of a funnel opening upwardly as illustrated and being provided with a charge pi e 33 which extended'downward to near bottom of the ma n refuse 29 and .is provided at its lower extremity with ajdiifuser or spreader as indicated at 34 which prevents agitation of the contents of the tank -29. The-tank 29 is pjr vided with a suitable drawolf pump of a y desired character 35 which has an intak 36 in pump barrel35",1preferably near the of thetank 29, as shown. 35f indlcat s the pump or piston rod, 35'thepiston, an 95ft, 35? thepump valves cont-rolling th --.d1s-' charge 37 over the funnel shaped dran 32,

the discharge 37 being at a point which will permit a suitable receptacle being placed under it to'permit the dirty oil from thepump to be receivedand removed and usedin such service as it may be fitted for but not'returned to the system again.' .The supply "tank 10' is provided with a suitable draw-ofl-pipe 38,

which also discharges into the tank 29 over:

funnel-shaped drain 32, as does the drawofii 39 from tank 17. The'draw-ofi pipe 38l from the supply tank is controlled by a suitable .valve as indicated at 40 and draw-off pipe 39 by valve 41. Theupper and clearer portion of the oil in the tank 29 when the tank becomes full is discharged back to the system again by passing over the overflow as indicated by the reference character l? and into tank 17 through pipes 43 and 16. I

In the operation of the improved system, as above described, the reservoir or gravity tank 10, the precipitation tank 13,- the filter 15, the drip receiving tank17, the pump 18, .the main refuse tank 29 audits exhaust pump 35 being inregular service, the oil passes from tank- 10 through the outlet which is above the bottom thereofthrough the oil, main 11"to the'location where it is to be used or hahdled in anydesi'red manner or wheredrips are liable to. occur. Drips are returned to the precipitation or settling tank 13 through the return drip main 12 preferably entering thetank-13 at a point considerably above the bottom thereof, as indicated ..to prevent agitating impurities lying 'upoii the bottom of the tank. The heavier impurities inthe drip are precipitated in .this tankvand lie'stagnant onthe bottom until the drain pipe of this tank is brought into service. By reason of the precipitation or settling which will take place in taiik13, the clearer oil will rise to the top 1 of the tank as indicated at 50, the stagnant impurities being indicated bythe reference; character 51 at the'hottom of the tank. The top clear oil overflows and is discharged through pipe 14, through filter 15, whence it passes by gravity through pipe 16 to drip receiving tank 17 entering the same near the bottom thereof.

Thepump 18 may be operatedto remove the clear oil from tank 17 through the in take 20 which is above the bottom of the tank as indicated, the oil passing through p p 9-1 eing open and valve 26 closed, and when the valve 41 is closed and valve 28 opened, the oil will be forced upwardly through pipe 27 and discharged into tank 10. The fact that the intake 20 within thetank 17 is above the bottomthereof, as

will prevent the precipitated impurities within the tank 17 being returned to the reservoir 01; gravity tank 10.

It. will be apparent'that in time during the normal ope'ration "of -'-the system the tanks- 10 and 17 will contain impurities in upon considerable quantities which will lie the bottoms of these tanks. When quanti ties of such impurities have accumulated the 1 same may be removed by first removing the clear oil from tanks 10 and 17, which is accomplished in the manner described throu h pipes 11; and 19' respectively. Then these iment or impurities in tanks-10 and 17 ma bevd elive'red to .the main refuse tank 29; tank 10 being emptied through discharge pipe 38 by opening valve 4:0 and tank 17 may be emptied of its impurities by the closing of the valve 21 in discharge pipe 19,

and valve 28 in pipe 27 which leads to supply tank 10, opening valves 26 and 41 respectively whence the impurities-will be received at the depressed portion 94 of tank 17 through intake 23 of discharge pipe22' thence through pipe 39 and into dram 32 whence these impurities reach the interior ,of tank 29 through pipe 33 and spreader 34:

atthe bottom thereof, which, as described,

provides to a considerable extent a non-dis- 'turbinginfio'w: into tank 29; The funnel shaped drain 32 which receives these'discharges of impurities from' tanks 10 and 17 may be protected with a suitable perforated plate or other form of screemas a screen, ofwoven wire, as indicated at 32. It will be apparent thatthe precipitation tank 13 will also become very dirty due to impurities -which will collect in the bottom thereof, as

this tank receives the return drip through pipe 12. Provision is thereforemade for into the main refuse tank 29 through dis-- charge pipe 30 controlled by valve 31, which discharge pipe likewise leads to drain 32 in the top of the main refuse tank 29. Thus the main refuse tank 29 serves to receive all these deposits of impurities and by reason of its peculiar construction of discharging theentire contents ofthis tank 1 spreader 34 ias described at the bottom of refuse tank 29 through drains 30, 38 and 39 1 respectively.

If-it is desired for any pirrpose to wit hdrew from the tank 29 portions. of the 'oil discharged therein clearer than may be ,ob-

.tained' through discha'rgespumpfiti, the tankv 29'" maybe provided with draw-ofi at suit-able heights from the bottom thereof, aeindicated at 6C- a'nd .61. I
